ProZilla: Multiple vulnerabilities
— GLSA 200411-31

ProZilla contains several buffer overflow vulnerabilities that can be
exploited by a malicious server to execute arbitrary code with the rights
of the user running ProZilla.

Affected Packages

Package

www-client/prozilla on all architectures

Affected versions

<= 1.3.7.3

Unaffected versions

Background

ProZilla is a download accelerator for Linux.

Description

ProZilla contains several exploitable buffer overflows in the code
handling the network protocols.

Impact

A remote attacker could setup a malicious server and entice a user to
retrieve files from that server using ProZilla. This could lead to the
execution of arbitrary code with the rights of the user running
ProZilla.

Workaround

There is no known workaround at this time.

Resolution

Currently, there is no released version of ProZilla that contains a fix
for these issues. The original author did not respond to our queries,
the code contains several other problems and more secure alternatives
exist. Therefore, the ProZilla package has been hard-masked prior to
complete removal from Portage, and current users are advised to unmerge
the package.
